APIs esp_btbb_enable and esp_btbb_disable are supposed to be used by 802.15.4 and Bluetooth module, and implemented with reference counter for resource management
modem retention: Support esp32c6 wifi MAC and baseband sleep retention
sleep_modem: wifi MAC modem wakeup protect in modem state before PMU trigger sleep enable request
sleep modem: provide a interface to get whether the Modem power domain is allowed to power off during sleep
add i2c_ana master header file to project
auto beacon: release PMU's lock on root clock source (it is locked in the PLL)
wifi receiving beacon frame in PMU modem state strongly depends on the BBPLL
clock, PMU will forcibly lock the root clock source as PLL, when the root
clock source of the software system is selected as PLL, we need to release
the root clock source locking.
When it is judged that the PLL is locked by PMU after wakeing up from the PMU
modem state, switch the root clock source to the PLL in the sleep process (a
critical section).
auto beacon: fix the failure to receive broadcast/multicast frames in modem state
When the multicast field in the beacon frame received in the PMU modem state is
True, the PMU switches to the PMU active state (the PMU waits for the HP LDO to
stabilize and then restores the MAC context) and starts to receive
broadcast/multicast frames (Broadcast/Multicast frames will be sent after a
minimum delay of 48 us after the beacon frame), because the PMU waits for the HP
LDO to stabilize too long (~154 us), which will cause broadcast/multicast frame
reception to be missed.
auto beacon: select the PLL clock source as the REGDMA backup clock source when the PMU switches to ACTIVE from MODEM state
update Digital Peripheral (M2A switch) REGDMA restore time parameter
auto beacon: fix the issue that only channel 1 can connect to AP in modem state
* add esp-phy-lib submodule
* move libphy.a and phy_init.c from esp_wifi to esp_phy
* move librtc.a from esp_wifi to esp_phy
* move libbtbb.a from bt to esp_phy
* corresponding updates to build system
